I did check my preferences for my time server and found that I didn't 
have a time server specified even though I had ntp enabled.  I guess my 
other question is, if I don't manually specify one, does it choose from 
any of the other ones as a default?  I noticed in my ntp.conf file there 
a bunch of time servers listed.  But does it restrict itself to the # 
--- OUR TIMESERVERS ----- section?
